Standard prostate cancer treatment decreases hormone levels, specifically estrogen, in the body which can lead to hot flashes, fatigue, decreased bone health, and cardiovascular and metabolic dysfunction. Transdermal estrogen may help to alleviate these symptoms. Androgen receptor signaling inhibitors work by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. LHRH analogues are a type of androgen deprivation therapy that blocks the use of androgen by the tumor cells. Giving estrogen with androgen receptor signaling inhibitor may improve quality of life in men with newly diagnosed or recurrent metastatic hormone sensitive prostate cancer.",[183,184,185],"Castration-Sensitive Prostate Adenocarcinoma","Metastatic Castration-Sensitive Prostate Adenocarcinoma","Stage IVB Prostate Cancer AJCC v8","NOT_YET_RECRUITING","2026-03-09",{"date":189,"type":190},"2026-03-12","ACTUAL",{"date":192,"type":177},"2026-08-01",{"date":194,"type":177},"2029-06-01",{"name":5,"class":6},1]
